Juniper Session Smart SD-WAN Deep Dive Part 1: 128 Technology and the Tunnel-Free Premise
Session Smart Routing didn't start as a Juniper project — it started as a session border controller team's bet that SD-WAN's entire tunnel-based premise was solving the wrong problem. This post covers 128 Technology's origin and the architectural break it made.

Juniper Session Smart SD-WAN Deep Dive Part 2: Secure Vector Routing — Tenants, Services, and Session Metadata
How Secure Vector Routing actually forwards a session: the tenant/service data model, the metadata the ingress router stamps on the first packet, and why that's enough to route symmetrically without a tunnel.

Juniper Session Smart SD-WAN Deep Dive Part 3: Session Smart Conductor, Mist, and the Two Control Planes
Session Smart Routers can be managed by an on-premises Conductor or by the Mist cloud. What each control plane actually does, how the multitenant policy model gets distributed, and how to choose between them.

Juniper Session Smart SD-WAN Deep Dive Part 4: WAN Assurance, Marvis, and AI-Native Operations
What "AI-native WAN" concretely means on the Mist side of Juniper's SD-WAN stack: WAN Assurance's telemetry model, Marvis's self-driving remediation, and where the AI layer actually earns its keep versus where it's a dashboard feature.

Juniper Session Smart SD-WAN Deep Dive Part 5: Zero Trust by Default — the SSR Security Model
Because SVR classifies every session against a tenant and a service before forwarding a single packet, deny-by-default segmentation is a property of the routing engine itself. What that buys, what it doesn't, and how SRX fills the gap.

Juniper Session Smart SD-WAN Deep Dive Part 6: Cloud Onramp and Multicloud
Extending Secure Vector Routing into AWS and Azure: virtual SSR instances, cloud regions treated as ordinary sites in the tenant/service model, and how that compares to the tunnel-based cloud onramp patterns already covered on this site.

Juniper Session Smart SD-WAN Deep Dive Part 7: The MPLS Cutover Playbook
A practical staged cutover from legacy MPLS to Session Smart Routing — overlay-first coexistence, tenant/service modelling before a single circuit changes, and why SVR's tunnel-free design changes the risk profile of the cutover weekend itself.

Juniper Session Smart SD-WAN Deep Dive Part 8: Failure Modes, Scale Limits, and a Five-Way Vendor Comparison
Series finale. What happens to the data plane when Conductor or Mist goes dark, where SSR's scale story sits, and Session Smart Routing lined up against Fortinet, Cisco/Viptela, Arista/VeloCloud, and Palo Alto/Prisma — five philosophies, one underlying question.
